Method for manufacturing high temperature resisting and high pressure resisting oil well cementation briquette through silicon bauxite ceramic microbeads
A method for manufacturing a high temperature resisting and high pressure resisting oil well cementation briquette through silicon bauxite ceramic microbeads comprises the steps that the silicon bauxite closed-hole hollow ceramic microbeads are manufactured, burdening, mixing, stirring and size mixing are carried out, 55-65wt percent of G-class oil well cement, 25-35wt percent of the silicon bauxite closed-hole hollow ceramic microbeads with the grain size of five microns to 50 microns, five to seven wt percent of pulverized fuel ash with the loss on ignition of 1.1 percent and the grain size of 20 microns to 50 microns, 1.5 to two wt percent of calcium oxide with the purity of 99.9 percent, 0.5-1.0wt percent of sodium sulfate and one to three wt percent of micro-silicon with the grain size of five microns to 20 microns are mixed, size mixing is carried out according to the water cement ratio of 0.5 to 0.7, the mixtures are poured into a set of two briquette molds with the length of 53 mm, the width of 53 mm and the height of 53 mm, are maintained in a water bath maintenance box for 24 hours and 48 hours respectively at the constant temperature of 52 DEG C, and are soaked in cold water for one hour after demolding, and a performance index test is carried out.
